Can't get my truck to fuel hard

400hp or so depending on the rest of the setup. You definately have a good ways to go before they are maxed out.

What else do you recommed in my setup that would help max it out? The dv's have been dynoed to around 700 hp so i wouldn't think they are holding me back. I am going to put the 4gsk back in so it should be able to have more usuable rpm. There is no fuel plate and the afc is gutted. I have a mack rack plug but it has not gone in yet. So other than the rack plug I am at a loss as to what I can do to make the truck fuel more ( move the rack more)...all this with the 181dv's and holders and the 180 injectors. It also has stock timing so changing that will help it pull harder in the upper rpm. But i am still lacking fuel and I have run out of ideas so...

Any other ideas on what to look for would be greatly appreciated?

You can do the plug without removing the pump.
Takes a little grinding on the timing case, but its been done many times before.

It doesn't take that long to remove the pump to put the plug in it. Then you don't run the risk of damaging the timing case either.
 
It can be done with the pump on, but when i put one in mine, I will be sliding the pump back just a little so that i dont have to grind my timing case.

Have you checked that the shutoff arm on the pump is pulling all the way up yet?
